IMPROVEMENT IN AReANo LAMP-.summe Specification forming part of Letters Patent No. 205,134, dated J une 18, 1878; application filed June 1, 188.

To all 'whom fit may concern city, county, and State of .New York, have invented a new au useful Improvement in Argand Lamp-B urners, which improvement is fully set forth in the vollowing specification, reference being had to the accompanying drawings, in which Figure l represents a vertical section ot'V my biuner in the line w fr, Fig. 2. Fig. 2 is aside view thereof, partly in section, some of the parts being detached. Fig. 3 ie a horizontal section in the line 'y y, Fig. 2. i

Similar letters indicate corresponding parts. My invention relates to that class of burners in which the wick-carrying device is operated by means of a key, licated at the bottom of the burner; and its chief aim` is to simplify the construction and operation )of such burners; another object being to prevent oil from settling on the outer surface of the key, so as to soil ones lingers in taking hold of the key.

My invention consists in the combinationof a spirally-grooved wick-carrier, a spirallygrooved draft-tube, on which the wick-carrier is fitted and rotates, and an inner rotating tube, having one or more downwardlyprojecting arms at its upper end, which extend over the upper edge of the draft-tube, are of equal `length thereto, or nearly so, and so engage with the wickcarrier that the latter is caused to partake of the motion ofthe inner tube,

but is permitted to move up and down, and hence when the inner tube is turned the wickcarrier becomes raised or lowered, as the case may be.

It also consists in the combination, with a drip-cup attached to .the lower end of the burner, and a key projecting from the bottom of said cup, of a supplemental drip-cup, which is located on the exterior and lower part of the main cup, so "as to catch any oil that may overflow from the dripcup,iand thus keep the key free oi' oil.

In the drawing, the letter A designates the outer shell or tube of my burner, which is connected to the supportingiarm of a lamp opposite to a hole, a; and B is the drafttube, which is secured to the outer shell at its lower end, so that a space is formed between them for the reception of oil. In the draft-tube B is formed a spiral groove, b. (l designates the Be '1t known that I, HENRY PREISE, of the 1 wick-carrier, constructed of a short tube or ring, which is fitted on the draft-tube B, and provided with a spiral groove, c, corresponding to the groove b, and spring-arms attached to said ring, as clearly shown in Fig. 2. D is the inner tube of the burner, which. is tted within the draft-tube B, and placed loosely therein. This inner tube is provided with two (more or less) arms, d, which are preferably formed in one piece therewith, and which project from the upper edge thereof` over the upper edge of the draft-tube B, and downward exterior to the latter, the arms being Vmade of a length equal to that of the drafttube, and being joined at their lower ends by a ring, f, placed loosely on the draft-tube. Said armsrd, moreover, engage with the wickcarrier C 5 and in order to effect this object, I provide the wick-carrierwith staples e, through which the arms d are caused to pass, so that the wick-carrier is permitted to move lengthwise of the armsd, and at the same time partake of any lateral motion of the arms.

In the example shown the inner tube D is made solid; but if desired it can be made in skeleton form. i

It will be perceived that when the inner tube D is turned the wickcarrier C is caused to move with it through the arms ol, and by the action of the spiral grooves b and c the carrier is caused to move up orl down, of which movement it is susceptible, as before stated.

On the lower end of the outer shell A is secured the usual drip-cup E, having holes for the admission of air.` Through this cup extends a key, F, which engages with a blade,

g, projecting from the lower end of the inner tube D, so that by means of this key said tube can be turned in either direction.

To the lower part of the drip-cup E, I attach a curved iiange, h, to form a supplemental `drip-cup, whereby any oil that may run down on the outer surface of the cup E is caught, and thus prevented from flowing over the key.

In the example shown, the key F is secured to the lower part of the drip-cup E, and the latter made to turn iu the lupper part of the cup; but the key can also be arranged in other` ways.

- The mitin advantages of ruy'burner over all other re7 first, no solde iig is require et the top, or that part 'thereof which is expoeerl to the flame, which latter obviously destroys the solder; second, the Wick-carrier need not be teken out in order to fasten the Wick, and. hence the dieulty experienced in replacing the carrier is obvia-ted; third, the position oi' tube, having one' or more downwardly-projecting arms et its upper eiie`f.,wl1ioh extend over the upper edge of the draft-tube, are of equal length thereto, or nearly soir-11d en gage with the wick-carrier, substantially in the marmer and for the purpose eet forth.

2. The combination, with the drip-cup E and key F, proj eotir.- g 'from the bottom of said cup, of a supplemental drip-cup situated ou the exterior and lower part of the main cup, substantially as and for the purpose set forth.

ln testimony that I ele-.im the foregoing l 'have hereunto eet my hand and seal this 30th day of Mey7 1.8i
